Your drivers are not installed properly. In Windows 10 goto the advanced settings and disable the signature verification first. After that install the driver for xperia z. It will work.

still no use after installing drivers for windows 10 and tried flashing stock rom Via flashtool.
but it showing Error while flashing the stock rom.. i think its un-resolvable problem i guess.. no luck...

Did you disable driver signature enforcement before installing the drivers?

There are plenty of threads about bootloop.
Also, this should be in Q&A section.
Anyway, make sure to install correct drivers. Ur flashmode is probably just fine.
Mine blinks and goes off also, but flashmode works.

Drivers are installed and driver signature has been disabled.. but finding error while flashing
wen i remove battery and connect Usb cable den the device shows tat it has connected in flash mode nor in fastboot mode... one of the IC is been missing or removed i dont know ill send the Pic after reaching home... i couldn't post the Screen Shot... ill do it today by night....
Pic has been attached below and can see the pointed area where the IC is missing or is it not available... plz let me know..

Hello Xda... I Can't Connect My bricked Phone to Pc. When i put it and turn it on flash mode it tells that failed to install the device drivers. Seus , PC Companion , Flashtool Can't Recognize it. can anyone help me? Thanks In advance.
First of all how you broke it? Second before you can proceed with seus or any other tool you need to install all drivers for your phone.....

How far does your phone boot-up?
Do you still see something on your screen?
Does the LED still light up (when connected to the charger/USB)?
If you haven't killed the boot-loader you should be able to recover the device with Flashtool ... if the boot-loader is dead I think there's no easy way to resurrect it.
Of course the unsolved question is if it would need a intact kernel as well AND if custom kernels actually support "Flash mode".

Finally I did it! Big Thanks to you. I Installed the drivers and it recognized. big thanks
Well, that's exactly from where Vlackrs and I already recovered our phones after a bad flash ("stuck at the Sony Ericsson logo").
Start Flashtool and select "Check drivers".
If it turns out as "OK" on all three checks it seems you have the drivers installed already.
If not ... try to install Gordon's Gate (should be included with Flashtool and called "ggsetup.exe").
Follow the instructions I wrote up here to restore the device.
Note that I did NOT use Flashtool 0.5 as 0.5.0.0, 0.5.0.1 and 0.5.0.2 failed to recognize the device (and yes, I replaced the "E15.properties" with the files posted in the Flashtool thread in the Development section) - Flashtool 0.2.9.1 did the trick for us.

Super Combo problem in my xperia x8.....

Well this is my first post here.
To be very short this is not a totally new problem. This is a combination of many problems that has made me totally helpless.
I had rooted my device using x8toolbox beta4, and installed a Gingerxperia V21 custom ROM.
After that i tried unlocking the bootloader, but flashtools continuously kept saying that my device was in MTP mode and strange enough there was no option in my phone's settings to change it.
So I went back to x8toolbox planning on installing the stock ROM back, when i saw busybox installer within.
I installed busybox 1.19.0 and then i asked x8toolbox to check the digitizer on my phone, AND THERE IT STARTED REBOOTING OVE AND OVER.
So now my phone can't connect to my pc for PCC repair or flashtools as MTP mode can't be switched off (and my phone won't turn on for the sd card to be read). And i am stuck with the Sony Ericsson Logo.
Please help me.....thanks in advance.
U have soft bricked your x8.
U can reset your x8 to original 2.1 with the help of following steps.
It's easy. Do it and rooted your phone again
forum.xda-developers.com/showthread.php?t=1570523
Officially corp via W8
Or just try Flashtool
i think your problem is flashing driver.. try to install on /flashtool/drivers/ the name of drivers is gordon gate.. but if your have a same problem after installed drivers, check your drivers on my computer/drivers.. or try for flashing on other computer..

Thanks for your answer..... But as I said my phone is still in MTP mode and doesn't seem to snap out of it. As i plug in my phone it turns on the green light and then starts rebooting as usual. Is it my driver 's issue? or is it just the mtp mode?? flashtool also says the same thing..:crying:
U cant keep it longer.
Open flashtool then select firmware and ok.
Wait till a screen appear.
Now connect ur phone by holiding back button.

But flashtools shows ERROR and flashing aborted and says that for 2011 line devices make sure your device is not in mtp mode....
Flashtools doesn't work that way....

It can't be, 3 weeks ago I had the same problem (MTP) .
I can't even install Apps via flashtool, so I try to connect to flashmode.
It works.
As I said try to Re-install windows.
Good Luck.

[Q] XZ won't pass "Device connected in flash mode" in SE Xperia Flasher

Hello,
I have some problems trying to flash my XZ. I'm using Xperia Flashing Tool 0.9.10.2 beta6 on Windows 8 x64 and whenever I try to flash my XZ flashing tool "gets stuck at "Device connected in flash mode" message after which it gets reconnected and if I try again same thing will happen.
So my question is, am I doing something wrong and if so, please advise.

thats better you now have a ADB device installed, you should now be able to put your phone into flashmode
power off your phone with usb diconnected, hold vol down and reconnect turned off phone to usb and you should now get green led and flashtool will say device connected in flashmode but you only have about a min in flashmode before phone reboots
Thank you for your help and effort but even now it keeps disconnecting device. I don't know where the problem is, maybe I'm not doing something as I should.
This is the procedure I was trying:
1) I select Flash device in flash tool
2) I select Flashmode mode
3) I choose which firmware to flash and click Flash so flash tool can start it's magic
4) When flash tool shows message that I can remove my device from USB and turn it off I do so
5) I also press volume down and reconnect the device with the PC.
6) Problem happens here
what about if flashtool isnt ready to flash file, does flashtool pick it up (4 and 5)
it will say device connected in flashmode with green led
Yeah, it does pick it up and displays a message "Device connected in flash mode" and after awhile "Device disconnected".

[SOLVED] Xperia SP - Locked Bootloader - Soft Brick

Hi everyone !
I've a Xperia SP which wont turn on anymore ... i installed a recovery, made a wipe factory, since it doesnt turn on :'(
Just so you know, i installed PhilZ Touch and TWRP (but i dont succeed to access them now, if someone know the manipulation ...)
However, i can access the Flash Mode, so I installed Flashboot (9.19.8), installed ALL the driver which were available in the "driver" directory, and tried to flash 4 differents TFT files, i tried on every USB port, with an officiel USB cable from Sony... didnt work
I've always the same error: Processing of system.sin finished with errors.
and then, the phone boot on "Sony" logo, then turn off, finally go in flash mode again endlessly as long as i let it plugged to my PC.
I dont know what to do, so here i am. Maybe all the rom i tried arent stock or arent compatible with my Locked bootloader ? Maybe its too low in battery (but before the recovery installation, it has something like 75% ...).
Thanks for your help !

Please use 0.9.18.6 or 0.9.19.8. Download the proper version of Flashtool here: http://www.flashtool.net/downloads.php
Then download the stock firmware by using Xperifirm that comes with the Flashtool, afterwards flash the stock firmware.
Also what Windows are you on?
I search for 6hours without anything, i post here ... and 10min after i found the problem ...
Flashtool isnt working for my phone after the 9.18.6 version o_o
so its ok now ! ty

I don't think so because this happened to me long ago when I tried to unlock bootloader.But I did something to the driver to work adb properly and it worked.And now I forgot that method and couldn't find in google also.So I'm really in big trouble.I just don't know why when I want to flash the stock rom and flashtool show in popup to power off the phone and press vol down button and connect to computer using usb cable but vol button don't work or not give any signal to computer.So I can't flash the rom.
Go to sony official site and download drivers.. ZR drivers dont exist but you can use drivers for Z, install those on your computer and use the fastboot method again and you should be fine.. Your phone is only soft bricked.. Hard brick is when there are absolutely no life in the phone at all.. Use a boot.img you know will work and no need to flash stock ROM once you're in recovery.. Unless you want to of course.. Custom ROM will boot your phone just fine
Also take your battery out and re-insert to make sure your phone is properly off.. Flashtool should also work after that

ZR driver exist in Sony developer website and I installed the driver but I don't know why my computer not recognizing my phone.My phone can turn into fastboot mode(blue light on when pressing vol up and connecting cable to pc) but when I type command "adb devices" the listed device is empty I mean no adb fastboot device found.I'm just asking the drivers are not working beacuse of windos 10?Actually when after I use custom rom I couldn't connect my phone to pc.So any driver can fix this problem?I searched really hard on google but couldn't find any proper sloutions.

Windows 10 is a pain to install drivers into.. But use fastboot in flashtool instead of flasmode.. Should recognize your phone and flash the boot image from there

I know you are trying to help me but I tried everything and nothing is working.I installed driver from flashtool but still no clue why pc not recognizing my phone.My phone is like a live junk.My phone soft bricked many times and I could recover my phone with flashtool so I know what to do but this problem is way more confusing.I just need to know what is causing this issue.
You've managed to install the drivers inc the lagan drivers in flashtool and connected your phone in fastboot mode with flashtool running and flashtool still don't recognize your phone? I've done that loads of times even with no drivers installed and flashtool has been able to recognize the device in fastboot.. If that's the case, then I'm sorry I'm not able to help any further as flashtool has always been my failsafe when things have gone wrong.. Adb and fastboot are usually no help for me in Windows 10..

My problem was created because local charger damaged my phone battery.So I couldn't turn on my device like yours.I replaced the battery and charger from Sony Center and now my phone is good as new.So Try to use other good battery(small or similer size that suites to your phone's battery pin)and see if your phone turns on without any issue.Then you can target the problem.
